Server load is under 1, nearly 0 io.
Ping between 200-300, normally it is around 50.
DC says their network is fine and it is my server.
So load under 1, almost no hard drive access, why is the ping so high?
I am facing high ping and packet loss issues with a server hosted at hetzner.de (CentOS + WHM)
For some unknown reason pings go high and stay like this (average 1500ms) until I reboot the server.
Here is a screenshot of tracert from server to me: [url]
On my way searching for an hosting provider, I try pinging every host.. some of them have packets lost, one between 20-30%.
View 10 Replies View RelatedI've run into an issue lately with a few servers that I support and I'm curious if anyone has any suggestions on how to approach the issue?
Scenario:
The server will stop responding to new network connections, I can ping it, but nothing more. When the DC looks at the server, they find the error " Out of Memory " on the console.
What is a good approach to troubleshooting these?
Here is what I do, if I'm off base, I'm here to learn and will read
find / -name "core.*" -ls | egrep core.[0-9]
**try and find software failure
df -h
**validate disk usage
** check /var/log/messages /var/log/dmesg
If I can't find anything obvious in those places, I start digging through the access_logs and error_log to try and find a giant influx of requests that could have hit the server too quickly to process thus filling the memory up.
In this case, I adjust the rlimits.
*shrug* This is not fixing the issue on a few servers and I'm curious how other people approach this problem? Could this be hardware?
I've been having this problem for the past week: everyday in the afternoon my dedicated server goes unresponsive for about an hour or so--you can FTP into it (upload and download work fine) and access the control panel, but it refuses to serve up any webpages / files through the browser (no one can access my site). Meanwhile the CPU / RAM seems to be just sitting there being completely unused. This problem just starts by itself and then goes away by itself somewhat regularly. Restarting the server has no effect on this.
I'm puzzled as to what the problem could possibly be or how I can fix it--any ideas? My server's running Fedora 6 / GoDaddy control panel.
15ms ping vs 40ms ping vs 170ms ping
Which you think is still acceptable for a website?
I have Apache 2.2 installed on Windows to host a web2py application using wsgi.
Apache crashed once stating it had run out of worker threads, so I inscreased ThreadsPerChild to 500. It has since crashed/become unresponsive without giving anything in the error log.
I set up mod_status, and am looking for understanding what I see when looking at server-status page.
It says 135 requests currently being processed, 365 idle worker. However I don't think there are 135 people connected.
Here's the request lines:
SrvPIDAccMSSReqConnChildSlotClientVHostRequest
0-1253840/0/0W138495448300.00.000.00
... the line above is repeated identically 125 times
0-1253840/32/32W000.00.460.46127.0.0.1dalgety-svr8.havelock.intGET /server-status HTTP/1.1
0-1253840/0/0W52400.00.000.00192.168.202.109dalgety-svr8.havelock.intGET /HubForms/ProjectFolderIndexing/index HTTP/1.1
[Code] ....
Question:
1) What are those 125 requests, and why are they not exiting. Are they anything to worry about? why is there no Client/VHost/Request? Could they be from the python process? Could they be what's causing the issue?
2) The Acc entry 0/121/121 on /HubForms/capacity_requests/index - is this representative of an issue?
3) When I restart Apache, it typically says "Terminating 375 threads that failed to exit" but that number doesn't match up with anything. Are these the idle threads?
Also I'm not sure what "restart" actually means, i.e. what stops and what stays (i.e. why am I on generation 0-12?).
4) Is any of this anything to do with why Apache becomes unresponsive, or should I be looking elsewhere?
I have a cPanel server with 4GB RAM
My server hangs time to time, once or twice a day. This is the last status when it happens.
Server Load 75.90 (2 cpus)
Memory Used 92 %
Swap Used 65.78 %
When I was still inside SSH when it happens, the processes I can see inside "top" are a lot of httpd processes.
So I "killall -9 httpd", I had to do it 30~40 times
#killall -9 httpd
#killall -9 httpd
#killall -9 httpd
x 30~40 times until no pid process found & the server load is back to normal.
Before that, I check httpd fullstatus, they look very normal, same goes to what I see inside WHM Apache status & cpu usage status.
At first I thought it was a memory problem after consulting with a server admin, so I replaced all 4GB new ram stick (such a waste)
My server is very slow, High CPU, High Apache load....
I got a new server and i had setup a script on it.
No server tweaks has been done.
I run a filehosting site so it gets very slow when traffic is high.
Here is some info:

I dont know much about server managment...
how to fix this so server doesnt go slow?
I have a site that is eating up my server resources and need to know what the best solution for this is. I'm thinking of getting another server just for mysql but do not know what specs the server should be to handle the current traffic/database load and have the site run smoothly without slowing down to a snail's pace.
An alternative is to get another server just for the videos being served and leave the database and html on the current server. This is where I'm stuck and don't know what route to take with this.
My current server stats:
Dual Xeon 5130
4GB RAM
250GB
50 Mbit/sec
CentOS 3.9
Website traffic stats:
15,000 visitors/day
150,000 pageviews/day
Serving videos
I've attached screenshots of top and bandwidth usage per day. Hopefully with this information you could tell me if I need another server or if there are any things I can do to the current server to help things move faster.
I recently purchased a Dedicated Server, and this is the first time I have ever used a Dedicated Server before, although I do have some experience with Linux. The problem I am having is that if you assign an Unused Dedicated IP to a domain using WHM the entire website that is assigned to that IP becomes inaccessible. I am able to ping the Dedicated IP, but that's about it. So the problem is probably that the Dedicated IP isn't pointing to the proper location where the website is, if you use the Server IP everything works fine.
So my question is what do I have to do to fix the problem and point the Dedicated IP to the proper location? Is it something that the Host has to do for you or is it just a simple file edit as root? I am using CentOS 5.3 64-bit as my Operating System with cPanel/WHM as my Control Panel.
I can't say that I can recommend CheapVPS's (VAServ) services to anyone. In the end of July, I bought a VPS from them.
Had some initial troubles with the set up - they accidently set up 2 VPS's for me and set the wrong amount of memory, but that was solved by sending a support ticket. Wanted Debian instead of CentOS, another support ticket.
In the end of August, I canceled it - mostly because I didn't need it anymore. However, September already came and I was charged for the VPS. I sent a ticket to their billing department asking for a refund, and they gave it to me, no problem there.
I go on with everyday life, until October comes. I guess I forgot to cancel the PayPal subscription for my VPS because I'm charged for it once again. I promptly cancel the subscription and fire off a support ticket.
This time, they're insanely slow to respond to this. I sent a ticket in on Oct 1. and I get a response on the 8th: they ask me for a PayPal transaction ID. I send it to them, and I haven't received any reply since.
On Oct. 15 I tried adding a new comment to my support ticket, but I still have not received any response.
Today, I try to nag their live chat salesperson and they tell me that they've "added a note on my ticket for the billing department".
I have 2 CPanel servers. I wanted to transfer multiple accounts via WHM but it gives me error that I cannot SSH into the other server.
I tried to ping the 2nd server from 1st server and it gives me:
root@s [~]# ping xxx.xxx.xxx.7
PING xxx.xxx.xxx.7 (xxx.xxx.xxx.7) 56(84) bytes of data.
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted
ping: sendmsg: Operation not permitted
cping: sendmsg: Operation not permitted
I added both server IP into allowed list inside my APF firewall on each server as well.
I rebooted both server earlier before, but it is still not solving my problem.
I have a problem with my server, that i can't not ping
Quote:
[root@server apf-0.9.6-2]# ping yahoo.com
ping: unknown host yahoo.com
But i can log in the ssh. i just installed apf, i check conf.apf to made sure there are port 80, but it still can't ping.
Has anyone had any more luck getting a response to either tickets or emails from Burton Hosting since the last thread here, which is months old? Our uptime remains decent, but with absolutely no responses to tickets (we have many outstanding by now) or emails (both to the standard network and support addresses and to individuals personally), and their phones disconnected, we of course are very concerned, and will probably be forced to look for a new host (I just hate the hassle!!) when our contract expires next month.
I did find in another forum posts about a Virante Marketing fiasco in which Burton was falsifying reviews, etc.---this does NOT sound like the Burton I knew before.
While we have exploratory emails out to DreamHost and a few others, I was hoping someone here would know a way to contact Burton---I just hate not knowing!
So I'm wondering what if anything I can do to get a better ping from my 1and1 server.
It's located in Wayne, PA and my ping floats around 70ms and I'm in South Lake Tahoe, CA. I only ask because there are servers with Peer1 hosted in New York, NY that give me a ping around 20ms.
Thanks for any help or advice.
Its a Windows Server 2008 Web Box.

globichen can explain about this.
ping timeout happen frequently.
this is the 2nd time happen in a week
i've submit a ticket regarding about this
customer service replies with server is online.
i'm not bashing their service but frequently ping timeout really makes my business down lately.
Loading website takes a few min & even couldn't access to server due to ping timeout.
I just installed a fresh new server with CSF
Soon I find out that my ping keeps dropping. The server was smoothly running, SSH is smooth, Website are loading fine, except I cannot ping my server. I disable SELINUX completely and it still doesn't help.
When I disable CSF, my server ping are responding back!
So I remove CSF installation and reinstall CSF, the same problem appear
How can I solve this issue?
My kernel is 2.6.18-92.1.6.el5PAE running on latest version of cPanel on CentOS 5.1
I got this domain hosted on my server where i can't ping or trace it. Every setting seem to be correct, the ip address, name server...etc. and other websites hosted on the server is working fine. i can reach other websites with no problem but not this domain.
how do i trouble shoot such problem? would deleted the website and recreate solve it?
has anyone ever come across such strange problem?
Here are the Servers IPs which are all located @ Malaysia but different datacenter:
Server 1:
Data Center: Brickfield
IP: 202.75.55.188
Server 2:
Data Center: Jaring
IP: 202.190.175.218
Server 2:
Data Center: Cyberjaya
IP: 202.71.103.132
I have a problem with one of my domain. Some users around the world cannot access the website, but they can ping and traceroute the server without any problems. I am able to access the website perfectly.
Site URL is www.djluv.in
And we are using IPB 2.2
Moreover if theres another domain on the same server, they can access it.
There are about 25-30 users who are facing this problem, but from different part of the world so I cant even say ISP problem.
APF has been shutdown, no Ban Filters on IPB or cpanel.
What are the possible reasons why they couldn't access the website? how to fix the problem?
Many a times websites hosted on my Red Hat Linux server would not open even though Apache and everthing else is up and running. When i hit reload on browser 4-5 times the website would load or i have to restart Apache and everything starts working normally.
Today when this problem resurfaced i did not restart Apache and looked for in apache logs and saw this strange entry in apache Error Log;
[client my.ip.xx.xx] script '/my/website/httproot/mdqt.php' not found or unable to stat
The above was in apache Error Log, above is my ip address, and i never requested a file named mdqt.php, in fact no file by the name mdqt.php even exist on my entire server.
I then looked for mdqt.php in error logs and saw several requests made for this file and from various IP addresses.
i understand this is what causes my http to die.

I use pingdom to alert me when sites go down. It would happen only once every few weeks, and I'd just reboot the VPS from my provider's control panel, however in the last 24 hours it has started doing it more and more often. The only change I have made in this time is to delete a few unused web sites.
When I get alerted, I check the the domains and they won't load. I look at the plesk control panel page thought and that does work.
I can SSH in, but I can't see anything that might work in the messages log.
I removed the plesk control panel error as that only seemed to happen once and is not happening anymore.
I saw quite a few entries in the /var/log/secure log and so I added iptables rules to only allow SSH access from my own IP and to DROP all other requests. It seemed fine for a while, but after 12 hours it has started becoming unresponsive again until reboot.
I'm having a very odd problem with one of my Linux (CentOS) cpanel server, all the server's services (http, ssh, mail, dns, etc) stop responding but the server still responds to ping.
I can't find anything wrong at all on the log files either, and the technicians that manually restart the server have told me that there is no indication of a problem on the screen.
I suspected a hardware issue and had the data center techs run a hardware test on the server but everything cleared ok.
This issue started a couple of weeks ago, no major upgrade or install took place when it started happening. From what i can see the halts are completely random, some times it goes for days without it happening and some times it happens just hours after the reboots.

I got 5 wordpress and 5 statics website on this server and 100 visitors by 24H00 each day.
Question 1 : Why the memory is so low and the swap so high ?
Question 2 : Why i don't find high usage process in top command ?
Question 3 How can i resolve this problem ?
do you know what my server having very strange problem my server load suddenly increas after every 2 or 3 days some time after 1 days but when we talk about those days in which server load is fine then that time server load very low almost 0.4 to 0.1 .
But on that high load day server load reached upto 500.
when i try to find out what wrong then i only get that there is too much connection of http when i kill httpd through this killall -KILL httpd then server load suddenly decrease and then stable.
I have a Quad Core Xeon server with 2 GB RAM. The server has some high traffic websites & at peak hours (4-5 hrs a day) the server load remains 10.0 to 50.0.
The sites on the server load very slow at these times. Here's the top result during heavy load
[url]
I have a couple of sites that are generating errors because the server load is too high and when I check service status I am seeing the following: Server Load 21.49 (8 cpus)
How can I tell if the problem is one of my sites in my VPS or a different site on a different VPS on the same server?
